e. Foucault is a young Parisian,
who, whilst engaged in some investigations with a pendulum in his
mother's cellar, made this discovery, as he claims it to be. We saw the
experiment repeated here on the same scale as it has recently been shown
at the Pantheon at Paris. A brass sphere, weighing about five pounds,
was suspended from the lofty ceiling by a piece of music wire, and made
to vibrate in one plane over a table graduated into degrees. After a few
vibrations, the direction of the pendulum appeared to be changed, as
though the table had moved round on its owns axis.

We passed an hour at the Egyptian Hall to see the opening of the
American Panorama of the Overland Route to California. It bids fair to
make a hit in London. Last Sunday, "great exhibition" sermons were
abundant in London. Exeter Hal, the largest place in London, holding
about five thousand persons, is to be used for three months for the
performance of divine service, to accommodate the strangers who crowd
the city. We all went, Sunday evening, and heard the Rev. Thomas Binney,
who has quite a reputation. The hall was as full as it could be, but we
did not think the discourse as good as it might be. It was rather
declamatory.

You no doubt remember how much our curiosity was excited by hearing that
Mr. Wyld was about to place a model of the globe, of gigantic
dimensions, in the great exhibition. Well, he was unable to obtain the
space required, and so he has erected a spacious building in Leicester
Square. This building is circular, with projecting entrances at the four
cardinal points of the compass. From the centre rises a graceful dome.
Here is placed the model of the earth, fifty-six feet in diameter. The
scale is about ten miles to an inch. The arrangement before used in the
construction of globes is reversed in this case, and the continents,
islands, and seas are seen on the _inner_ surface. This seems like
turning the world, not upside down, but inside out. The mountains and
land are elevated to a scale. The spectators travel round the globe on
winding staircases, at the distance of a few feet from the surface. I
went the other morning to the model, but was far less interested than I
expected. The rest of the party were not present, and are willing to
take my report. I heard that Mr. Wyld has spent twelve thousand pounds
upon his undertaking.

We selected a fine afternoon to visit the Zooelogical Gardens in the
Regent's Park, and, of course,
